Turn your own iPhone, iPad, or Mac into a private home security camera. Set an old device to watch a room and its screen dims to a discreet dark monitor view — one that always shows a clear recording indicator, so it is never hidden — while it detects motion, saves event clips, and streams live to your other devices. Wake it any time with a press-and-hold. PRIVATE BY DESIGN Unlike typical CCTV apps, SentryBlack has no company servers watching your home. Your video stays on YOUR devices and YOUR own private iCloud — never our cloud, and never a third-party cloud you did not choose. • Live view goes device-to-device and is end-to-end encrypted. • If your network blocks a direct connection, you can optionally add a relay server of your own — the video through it stays end-to-end encrypted and the relay cannot decrypt it. SentryBlack provides no relay server, and this setting is off unless you fill it in. • Cameras, motion alerts, and clips sync only through your private iCloud. • No account, no sign-up, no tracking. USE ANY DEVICE AS A CAMERA • The screen dims to a dark monitor view with an always-on "REC" indicator and timer — discreet and power-saving, but never blank. • On-device motion detection saves a clip and snapshot of every event. • Press and hold to wake the screen. MONITOR FROM ANYWHERE • On another device signed into the same iCloud, tap Monitor to see all your cameras. • Get instant push alerts with a snapshot the moment motion is detected. • Watch live video — fastest on the same Wi-Fi, and end-to-end encrypted everywhere. SENTRYBLACK PRO The free version records with motion detection, sends cross-device alerts, and streams live on your Wi-Fi (with a small banner ad on non-camera screens; iPhone and iPad only — the Mac app has no ads). SentryBlack Pro adds: • Cloud clip backup to your own iCloud • Unlimited event history • HD live view • Person detection & motion zones • Multiple cameras • No ads Pro is an auto-renewing subscription (monthly or yearly) with a 3-day free trial. One subscription works on iPhone, iPad, and Mac. Payment is charged to your Apple Account; it renews automatically unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in Settings. Note: because Apple stops the camera when an app is in the background or the device is locked, a camera device must stay on and in the app while on duty — keeping it plugged in is recommended. Please use SentryBlack only to monitor your own property and spaces.

Verdict
The clearest difference is in-app purchases: SentryGo at none against SentryBlack's 2. SentryGo also leads on ads (none vs shown) and iOS requirement (15.6 vs 17.0). SentryBlack's advantage is update cadence (fortnightly vs every 3 months). On price and device support there is nothing between them.
